Summary:Chemical analyses were made on 82 specimens of the Ibaragi granitic complex, Osaka Prefecture, central Japan, by XRF and gamma -ray spectrometric methods. This granitic complex consists of two masses: the Nose and Myoken plutons. The Nose pluton shows smooth trends in major- and trace-element-SiO2 diagrams, while the Myoken pluton data is clustered in a narrow range of SiO2. The authors consider that the former was formed by the differentiation of a parental magma, and the latter by magma mixing. [K.O.]
